any perfect circle is x^2 y^2 = r^2your question is defining the limit within a calculus equation - the limit of x as x approaches 1. this will help you figure out what is the tangent (aka the surface) of particular contact point(s) - of the sphere. In 2 dimensions (circle) you will need 2 points to figure out the tangent. As your 2 points become infinitely close you will obtain a true tangentas your 2 (or 3) points come closer together (0.0001 units apart, vs 0.0000001 units apart, yourIn 3 dimensions (sphere) you will 3 points and that the equation for a sphere is x^2 y^2 z^2 = r^2 but thats even more math i'm not able to answercheck out khanacademy .com for its lesson on limits Abusive comment hidden.
